Connection to network

[Kening]

Samsung Galaxy S20 keeps telling me "Not registered to network" when I try to call someone or send a message or search Google.   Can someone help here?  I've tried everything!

@Kening Could be a faulty sim. Do you have an O2 store nearby you can call into and get them to swap sims for you? If not contact O2 via social media and they should be able to get one sent to you:

Facebook (https://o2uk.co/O2CFB), Twitter (https://o2uk.co/O2CTW), or Instagram (https://o2uk.co/O2CIG)

Thanks, Bambino.  Will try that.........................but will I then have to transfer stuff onto the new SIM?   Not sure how these things work!!  Kening

@Kening The only thing that transfers is your phone number. Everything else is stored on your phone and with Google.

Thanks again, Bambino.  Kening

Have followed Bambino's advice and changed my Sim card.  Excellent help from O2 here.   Have inserted the new Sim card and, with the help from O2, the "Sim Swap" was made and all now seems well.   Phone is now registering with the network and all seems good.   So thank you Bambino and O2.
